The subsidiary of United Technologies Corp. said Tuesday that it's responding to "business and economic conditions." The company, based in East Hartford, Conn., said the cuts are necessary to remain competitive.

Pratt & Whitney announced in December it will lay off 80 hourly employees and eliminate 20 other jobs through buyouts.

The company employs about 36,000 workers worldwide.

Company President David Hess said in May that sales are expected to double, to $24 billion, by the end of the decade. But he said Pratt & Whitney must navigate a few transitional years of high fuel costs and a weak economic recovery that are pressuring airline customers.
